That's a large raise, do I call it? It's my line up to the river ok or do I have to bet the flop ? Villain it's 17/15, 2+ aggression on all streets.

Lead flop, if not, c/r flop.
Instacall river, you have the second nuts.

you should just about always bet big when you flop a flush, because you'll usually get action. people aren't going to put you on a flopped flush. they're going to put you on a made hand that's afraid of the flush, or a draw. as played, that's a super easy call.
